Solution description

5-speed controller for AC fan with a single-phase motor, equipped with thermal contacts. The maximum motor current is 10 A. Typically, it regulates fan speed in HVAC applications. The fan speed can be selected via the 5-step rotary switch. In OFF position (zero), the motor is disabled. The TK monitoring function deactivates the motor in case of overheating. The digital input can be used for remote start-stop commands. After a power failure, the motor will automatically restart. The autotransformer technology generates a motor voltage with a perfect sinusoidal shape. This guarantees quiet motor operation.

5-speed transformer fan speed controller for single-phase motors with thermal contact. The (combined) maximum current is 10 A. The fan speed is set with the rotary switch in OFF position. The motor can be remotely switched on or off via digital input. The TK monitoring function stops the motor in case of overheating. The motor restarts automatically after a power failure. Alarm and uncontrolled outputs can be used to control external devices to issue warnings or check normal operation. The fan speed is controlled by a five-stage reduction of the motor voltage through an automatic transformer. This technology results in a perfectly sinusoidal output voltage and guarantees quiet motor operation. The enclosure can be surface mounted and is IP54 rated against dirt, dust and moisture.
